For more than a year, Eminence saw the Keurig stock on a downward spiral. Today, the maker of single-serve coffee brewers announced it was being acquired by JAB Group for $92 per share. That share purchase price is 78 percent higher than the company’s closing price on Friday where it closed at $51.70. When compared with the stock’s 20-day average, the premium is 89 percent — the largest in beverage-industry history for any acquisition above $5 billion, according to Bloomberg.
